Another thing that might be good to happen is that the author of RAWerter could change it so his displayed (and copied-to-clipboard) value for light gray is much darker.
My logoeditor deliberately makes the light gray look really dark because that's how it looks on the player. My values are:
GrayDisplayValue0=0
GrayDisplayValue1=80
GrayDisplayValue2=96
GrayDisplayValue3=255
RAWerter's values are 0, 83, 166, 255, so all but the light gray are close enough to begin with.
I suggest RAWerter should display its light gray at somewhere between 96 and 160. Perhaps 129 or something, that would be a good compromise for most color-reduction algorithms (with cutoffs at 128 for middle gray).
